DUST GATCHEB FOB RADIATOBS.

Application filed November 27, 1925. Serial No. 71,853.

My invention relates to dust catchers for radiators; that is, to devices used In connection with radiators of the type used for heat-v in buildings and the like, for settling and 110 ding particles of dust and smoke, in order to facilitate their removal from the air circulating about the radiator.

More particularly stated, I seek'to produce a dust catcher specially adapted for use with ordinary household radiators and the casings customarily employed with such radiators, my device having provision for facilitating the dislodgement and removal of dust and dirt after the separation thereof from the air.

More particula1'ly -stated,I provide a textile fabric. upon which the'particles of dust and smoke are settled automatically and re tained by the fabric, after which the fabric is cleaned and restored toduty.

My improved dust catcher is preferably mounted withiniand carried by a casing, in which the radiator is housed.

Reference is made to the accompanying drawings forming a part of this specification and in which like reference characters indicate like parts throughout the several figures.

Figure 1 is partly a front elevation and partly a vertical section of my improved dust catcher.

Figure 2 is a section on the line 2--2 of Figure 1, looking in the direction indicated by the arrows.

Figure 3 is an end elevation of the device.

A radiator is shown at 4, and is provided with legs 5 upon which it is supported.

Connected with the radiator is a steam or hot water fixture 6 controllable by a hand valve 7 in the usual manner.

A casing 8, made of metal or other material capable of withstanding a moderate degree of heat, is provided and used as a housmg for the. radiator. The purpose of the casing is to prevent smoke and dust, carried by the air as it circulates around the radiator, from settling upon walls, curtains, furniture, and the like, in immediate proximity to the radiator. I

As is well known in this art, practically all objects located close to a radiator soon become soiled or blackened by particles of smoke and dust, unless the radiator is en-' closed in a casing.

The casing 8 is provided with a back wall 9 and a front wall 10, the back wall being free from openings'and disposed at the back textile material of the radiator, or in other words, between the, radiator and the adjacent wall of the room. The front wall of the radiator is provided with openings 11 to allowthe escape of hot air which circulates in consequence of the heating of the radiator. These 0 enings 11 are so arranged as to discharge ot air, laden, of course, with the particles of smoke and dust as aforesaid, out into the open space of the room where the radiator. is located.

-Up to this point, the construction of the radiator and easing may be of the type heretofore used.

The walls 9 and 10 of the radiator are each cut away at the bottom, which is thereby provided with an edge 12, located a little distance above the floor. The casing is provided with end walls 13 and 14, which are slightly cut away at the sides, as may be understood from Figures 2 and 3.

Extending lengthwise through the casing, and supported by the end walls 13 and 14 thereof, are a pair of revoluble shafts 15 and 16, and partially woundupon these two shafts is a length web 17, in the form of a textile fabric. This-textile fabric may be cheese cloth, mosquito netting of small mesh sleazy cloth, or in fact almost any sort of through which air can circulate rather freely, and which is capable of holding particles of dust or smoke which settle upon it and lodge throughout its substance, as the air passes through it. The textile fabric 17, being wound upon the revoluble shafts 15 and 16, is thereby formed into rolls 18 and 19, as indicated more particularly in Fi 'ure 2.

Extending through the casing and supported by the end walls thereof are guide rods 20, 21, 22 and 23, made of metal such as steel, and which are preferably smooth. The two guide rods 20 and 21 are located in close proximity to the back wall 9, but the guide rods 22 and 23 are spaced a little distance from the front wall'lO, adjacent which they are located. The web of textile fabric, partially wound upon the shaft 15 and thus formed into the roll 18 as above described extends therefrom obliquely upward to the right according to Figure 2, thus engaging the rod 20, thence extending straight upwardly into engagement with the ing the rod 23, thence extendingobliquely I downward and formed into the roll .19 carried by the shaft 16. I The shafts 20, 21, 22 and 23 are fitted at their ends with nuts 24 for holding them in position. I j

The two revoluble shafts 15 and 16 are provided with end ortions 25, 26, which are squared or rendere angular as indicated in F1 res 1 and 3. g

.provide a winding crank 27 of. the form indicated in Figure 3, and this winding crank can be detachably fitted upon the end portion 25 or 26, and turned by hand so as tocause the shaft to revolve.

By placing the winding crank 27 upon the angular end 26 of the shaft 16, and turning to the left according to Figure 2, the shaft 16 is rotated in' a counter-clockwise direcin any desire tion according to this figure. By detaching the'winding crank and fittin it upon the -it out in the wind for a few hours.

The operation of my device is as follows:

The various parts being arranged and assembled the operator turns one of the revoluble shafts, say the one numbered 16, and turns it in a clockwise direction according to Figure 2 until the roll 18 becomes pretty large and the roll 19 relatively small.

The ra iatorbeing in action, its heat causes the air around it to flow upwardly within the casing, and to make its escape by passing through the openings 11 and the POItlOIl of the web 17 stretched between the rods 22 and 23, as indicated at the left of Figure 2 Any particles of dust or smoke, present 111 the air thus circulated, lodge upon the said portion of the web stretched betweenjthe rods 22 and 23 and are thus sifted out, and confined upon the surface of the web, or lodged within its substance. Thus the air passing from the radiator out into the room, is freed of its particles of dust and smoke,;snd rendered in good ondition for breathing.

As may be seen from the foregoing description, my invention tends to prevent the deposit of dust and smoke upon curtains,

walls of the room, furniture and the like, and at the same time renders the air suitable for breathing.

' comprising After one portion of the web is soiled and. blackened by the. dust and smoke passing throu h scribed so as to wind up the portion thus affected, and to leave exposed another portion stretched between the rods 22 and 23.

Within reasonable limits the web may be of any desired length, and depending upon its length relatively to the size of the radiator casing, may be shifted once, twice, or even a larger number of times, in the same direction. This means that the web isexposed step by step to the action of the dust and smoke, until practically'all portions of the webhavebecome dirty, and the web requires cleaning.

I do not limit myself to the precise construction shown, as variationsmay be made therein without departingv from my invention, the spirit of which is. commensurate with my claims.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is as follows:

1. A device of the character described, comprising a radiator casing for fitting over a radiator and provided with openings through which air can escape when circulated y the heat of said radiator, a plurality of rods carried by said casing and extending through said casing and in proximity to the radiator, a member of textile fabric engaging said rods and partially supported thereby, said member of textile fabric being of a texture suitable for arresting and retainingparticles of dust and smoke, and mechit, the web is shifted as above. de-
